You may ask yourself, why on earth would anyone pay 99 cents for an iPhone app whose sole purpose is to flash bright, solid colors? We certainly wouldn't recommend it, but Handy Light has a great little Easter egg that undoubtedly doesn't jive with the folks at Cupertino HQ. Like Nullriver'sNetshare app before it, this little piece of software allows for SOCKS proxy tethering, without having to sign up for AT&T's tethering plan. Instructions available via the video below, and if you're looking to pick up the app yourself, better hurry -- we can't imagine Apple will let this one stay in the store for very much longer.
Update: Looks like the app's been pulled. Ye who snoozes, ergo must lose. If you did manage to nab and the video below isn't working (we see it just fine), check out App Shopper for more detailed, text-based instructions.
